IMPROVEMENT IN WATER-ELEVATORS FOR WELLS.

Specification forming part of Letters Patent No. 153,005, dated July 14,1874; application filed March 2S, 1874. v

To all whom it may concern:

Be it known that I, WILLIAM MASON, of the city and county of Providence,Rhode Island, have invented a new and useful Improvement inVVater-Elevator for Wells, of which the following is a specication:

Figure 1 is a side view of my improved water-elevator, shown as appliedto a well-curb, the curb being shown in section, and Fig. 2 is a detailview illustrating the operation of the trip-arm and its friction wheelor roller.

My invention has for its Object to furnish au improved device forraising water in wells, and more especially in deep wells, which shallbe simple in construction and convenient in use, being so constructed asto enable the water to be raised with more ease than when the ordinaryelevators are used.-

The invention will first be fully described, and then pointed out in theclaim.

A represents a well-curb, which is provided with a spout, B, in theordinary manner. C is the bucket, which may be made of metal or wood,and which should be provided with a valve, I), in its bottom, to allowit to be readily Iilled with water when lowered. To the bail of thebucket C is attached one end of a rope, E, which passes over a pulley,F, attached to a shaft, G, which revolves in bearings in the upper partof curb A, and to one end of which is attached the crank H, by which itis turned to raise and lower the bucket. rlhe crank H may be providedwith .one or more short arms, h', to strike against a button, pin, orother stop attached to the curb A, to support the bucket in any desiredposition. The rope E passes around a pulley, I, pivoted to a'weight, J.The other end of the rope E is secured to the upper part of the curb A,as shown at the point K in Fig. 1. In the inner part of the spout B ispivoted the outer end of a bent bar or arm, L, the inner end of whichprojects sufficiently to catch upon the edge ofthe bucket O as it risesabove the inner end of the said spout B, and tillit discharges the waterautomatically' into said spout. Upon the lower side of the inner end ofthe arm L is pivoted a small friction wheel or roller, M, which, shouldthe bucket C rise in such a position that-the arm L may catch upon theedge of said bucket near one end of the bail, may roll along said edgeto a position midway between the ends of the saidfl'iail, so as todischarge the water properly into the spout B. Without thefriction-roller M the arm L would not slip upon the edge of the bucketC, especially in the case of a wooden bucket, but would remain where itfirst took hold of it, so that the water would not always be properlydischargedinto the spout.

Having thus described my invention, I claim as new and desire to secureby Letters Pat; ent- The pivoted arm L and friction wheel or roller M,for tilting the bucket C as it rises above the spout B, substantially asherein shown and described.
